Monts de Oca, N., Diaz, L., McMahen, D. et al. 2014. The use of lean management principles to enhance a nonhuman primate environmental enrichment program. American Association for Laboratory Animal Science [AALAS]

Sewage back-up and overflows in the rooms of our primate facility initiated an analysis of the factors contributing to the clogging of the drains. An investigation reviewing the materials responsible for the clogging of the...

Schillaci, T. T., Bishop, B. 2014. Effects of needle gauge on blood quality and potential for bruising with repeated blood collections in cynomolgus macaques. American Association for Laboratory Animal Science [AALAS] Meeting

Obtaining quality blood samples while minimizing animal trauma related to venipuncture continues to be an important area of focus within the laboratory animal environment as it relates to both animal welfare and sample integrity. A...

Bennett, A. J., Perkins, C. M., Harty, N. M. et al. 2014. Assessment of foraging devices as a model for decision-making in nonhuman primate environmental enrichment. JAALAS 53(5), 452-463.

Continued progress to move evidence-based best practices into community and regulatory animal welfare standards depends in part on developing common metrics to assess cost, benefit, and relative value. Here we describe a model approach to...

Camus, S. M. J., Rochais, C., Blois-Heulin, C. et al. 2014. Depressive-like behavioral profiles in captive-bred single- and socially-housed rhesus and cynomolgus macaques: A species comparison. Frontiers in Behavioral Neuroscience 8, 47.

Background: To unravel the causes of major depressive disorder (MDD), the third leading cause of disease burden around the world, ethological animal models have recently been proposed. Our previous studies highlighted a depressive-like profile among...

Xing, G., Lu, J., Hu, M. et al. 2015. Effects of group housing on ECG assessment in conscious cynomolgus monkeys. Journal of Pharmacological and Toxicological Methods 75, 44-51.

Assessing the cardiovascular safety of new chemical or biological entities is important during pre-clinical development. Electrocardiogram (ECG) assessments in non-human primate (NHP) toxicology studies are often made using non-invasive telemetry systems. We investigated whether ECG...

Pearson, B. L., Reeder, D. M., Judge, P. G. 2015. Crowding increases salivary cortisol but not self-directed behavior in captive baboons. American Journal of Primatology 77, 462-67.

Reduced space can lead to crowding in social animals. Crowding increases the risk of agonistic interactions that, in turn, may require additional physiological defensive coping mechanisms affecting health. To determine the stress induced from increased...

Bloomsmith, M., Kim, N., Franklin, A. et al. 2015. Positive reinforcement methods to train chimpanzees to cooperate with urine collection. JAALAS 54, 66-69.

Positive reinforcement training can be used in many ways to enhance the welfare of captive primates. Training for biologic sample collection is one application of positive reinforcement training. In this study, 35 adult female chimpanzees...

In modern zoos, training should be an integral component of the animal care and management. The benefits of training include the opportunity for positive interactions with caretakers. This study was carried out with a group...

Wergrd, E., Temrin, H., Forkman, B. et al. 2015. Training pair-housed Rhesus macaques (Macaca mulatta) using a combination of negative and positive reinforcement. Behavioural Processes 113, 51-59.

When training animals, time is sometimes a limiting factor hampering the use of positive reinforcement training (PRT) exclusively. The aim of this study was to evaluate the effects of a combination of negative and positive...
